  • Drinking
  • Cooking
  • Making Ice
  • Brushing Teeth
  • Washing Dishes

If you have friends or relatives living in these areas please help pass the word by checking to make sure they know they need to boil their water.

We know living with Boil Water Notices can be frustrating. We’re doing everything we can to improve water quality and remove the notices as soon as possible whilst keeping people healthy. more information about each current boil water notice can be found below.

We’ll update people on where how long works are expected to take as soon as we can.


The Suburban BWN has been in place since the November 2016 earthquake.

Post-earthquake investigations identified intake damage and source changes on top of what was already limited protection. Suitable protection would be provided by intake improvements, storage and treatment.

A water safety plan has been approved and the work needed to lift the notice is scheduled for the 2019/2020 financial year.

Once improvement works are undertaken and consecutive complying test results are received lifting the BWN can be considered subject to agreement by Canterbury DHB.

East Coast: 

The East Coast scheme is a very large rural supply used predominately for stock. A boil water notice has been in place since before the November 2016 earthquake and will remain in place for the foreseeable future until decisions about the future of the scheme are made.

Post-earthquake investigations highlighted the limited protection measures. Due to it's size, it would not be practical or efficient to treat the entire scheme. Discussions with the scheme committee and Canterbury DHB  are underway to look at future options including the potential to classify the scheme as a Rural Agricultural Supply.

Once decisions are made, required improvement works undertaken and consecutive complying test results are received, lifting the BWN can be considered subject to agreement by Canterbury DHB.


The Fernleigh scheme is managed and operated by Downer. Council’s role is only to monitor scheme performance.

The BWN was put in place on 24 December after monitoring detected an E-coli transgression. The scheme has received three clear consecutive tests since Christmas, however Canterbury DHB has required the BWN until an investigation by Downer into the contamination source is completed.
